Smosh, if there is sealer around the "jet plug" there could easily be some floating around inside or lodged in the carb. Sealers of any kind are not recommended on carbs for that reason!
Since you say it makes some temp in the exhaust but won't run also sounds like ignition and I don't mean spark. Check again for proper plug wiring and are you SURE the timing has not been moved? The heat should be in the cylinders and not in the exhaust. If the timing is lazy it can be firing just before the E valve opens not just after it closes.
